Steps to find the percentage of a number

Method 1: Using Proportions

Let's find 15% of 1 using proportion.

15% is 15 out of 100.

\[ \frac{ 15 }{100} \]

Write the proportion to find x out of 1.

\[ \frac{ 15 }{100} = \frac{x}{ 1 } \]

Cross-multiply: 15 × 1 = 100x

\[ 15 \cdot 1 = 100x \]

Solve for x: (15 × 1) ÷ 100 = x

\[ \frac{ 15 }{100} = x \]

Hence, 15% of 1 is 0.15.

Method 2: Keyword-Based

Use keywords: "of" means multiply.

Convert 15% to decimal: 0.15

\[ x = 1 \cdot 0.15 \]

Multiply 1 × 0.15 = 0.15

So, 15% of 1 is 0.15.

Method 3: Formula-Based

Use the formula: percent × whole = part

Convert 15% to decimal: 0.15

\[ \text{Percentage} \cdot \text{Whole} = \text{Part} \]

1 × 0.15 = 0.15

Thus, 15% of 1 is 0.15.
